VID: (Virtual LAN ID) It is an definite number of ID which number is from 1 to 4094.
PVID: (Port VID) It is an untagged member from 1 to 4094 of default VLAN.
Link Type: Access means the port can receive or send untagged packets.
Trunk means that the prot can receive or send tagged packets.
The EFM modem initially default configures one VLAN , VID=1.
A port such as LAN1 to 4, DSL or sniffing can have only one PVID, but can have as many VID
as the EFM modem has memory in its VLAN table to store them.
Ports in the same VLAN group share the same frame broadcast domin thus increase network
performance through reduced boardcast traffic. VLAN groups can be modified at any time by
adding, moving or changing ports without any re-cabling.
